Embodiment Construction

[0011] as attached figure 1 As shown, the process of applying for wireless positioning in the present invention is as follows:

[0012] 1. Use the GPS device equipped by the observer to obtain the observer's location information, and display the observer's location on the electronic map;

[0013] 2. At the same time, obtain the distribution map of the information energy of the tracking target at the observer's current position in various directions, and record it on the electronic map;

[0014] 3. The observer goes around the target, repeats the action of step 1, and at the same time looks for the point with the largest signal energy in the direction of the observer's trajectory as a peak candidate point, and displays its energy distribution; finds the trough of the information energy extreme value to find the point on the observer's trajectory Other peaks are used as other peak candidate points; the peak candidate points are comprehensively evaluated to obtain the possible p...

Abstract

The invention discloses a wireless positioning method, belonging to the technical field of information. The wireless positioning method comprises the following steps that: an observer moves around a target for a circle and simultaneously records a signal energy distribution diagram of a movement track through allocating GPS (Global Positioning System) equipment, an electronic map and equipment capable of distinguishing target signal energy strength and direction by the observer; the observer searches a peak value point of an observation point energy extreme value and takes the point a candidate point; and three models are used for compressively estimating a signal scene to obtain an accurate position of the target. When the direction of the energy extreme value of the observation point is conflicted with the region of the target, the direction of a large-sized object around the observation point is used for revising the direction of a signal, so as to realize the accurate positioning. The wireless positioning method disclosed by the invention can improve the accuracy of the wireless positioning and can reduce the complexity of a positioning process.

Description

technical field [0001] The application of the present invention discloses a wireless positioning method in the field of information technology, which uses the signal scene of the observer's moving process to improve the positioning accuracy. Background technique [0002] At present, the domestic wireless positioning technology for mobile communication terminals is mainly based on signal energy and various time difference methods. Many commercialized wireless positioning technologies and patents are based on the geographical information, energy, and signal time difference of the base station. At the same time, since they are generally initiated on the network or mobile phone, they cannot be used to achieve positioning from the perspective of observers. These are methods of proactive identification and localization. In the era of 2G and 2.5G, the wireless positioning method for observers can be realized by using the method of pseudo-base station using the time difference meth...
